Two test objects of concrete frame behavior against lateral loading were performed by applying structural analysis with the wall as diagonal reinforcement in modeling. The results of the structural analysis indicated that concrete frames with walls have better performance than concrete frames without walls. Twelve objects consisting of the frame without the wall, frame with the wall, and frames with a group of steel and bamboo as diagonal reinforcement at brick walls and concrete panel walls were tested at the laboratory with monotonic lateral forces that work parallel to the wall as the illustration of earthquake loads. The diagonal reinforcement elements can spread the force received by the wall and increase the strength of the wall as well as enhance the stiffness of the structural system at once. Bracing contributes to increasing the strength, especially in resisting the compressive forces due to the earthquake loads. Deformation occurs in the opposite direction between compression path and tension path at the diagonal area. The failure in the concrete frame can be caused by the in-plane force parallel to the wall. Bamboo is quite effective to be used as a substitute for steel reinforcement as bracing material despite its shortage of steel quality. 1 Introduction Based on SNI 2847:2013, walls only function as a non-structural component instead of as a load receiver, while in structural design the wall is only assumed as a load. In fact, the interaction between walls and concrete frames is often overlooked. Concrete panel walls became one of the advanced technological developments in precast concrete. Currently, the use of infill panel walls is widely selected and applied in construction practices rather than the use of infill brick walls. It is due to the property of panels that they have relatively light weight, therefore it will reduce the weight of a construction. With such a property, it will have positive contributions, especially in areas affected by earthquake loads, including Indonesia. In addition, this technology can reduce costs in the construction process. Moreover, another advantage of using concrete panel walls is the easy implementation of the dissembled construction. * Corresponding author: [email protected]
